While usually described as a metal version of the A158, this watch is more reminds me of a re-re-issue of the Casiotron. I am not sure why Casio did not use the Casiotron name on these watches. With a metal case, mineral crystal, and milanese watch band, it is much of what I had wanted Casio to release in their classic watch line. However, there are a few things that could stand to be improved. I do not like any of Casio's negative displays, an this one is particularly bad; only being legible in direct light or with the illumination on. This can be changed by swapping out the movement with a model A1000d or A700 Casio, but this adds expense to the purchase. I also wish that Casio would use a sapphire crystal, although I cannot fault them for using mineral at the current price point.
